Abstract

A fuel control system is provided for a gas turbine (26, 6) engine having a core engine (2) comprising at least one core engine (2) spool in which a compressor (4) and a turbine (26, 6) are interconnected by a shaft (28, 8). The system includes a first engine sensor (42, 44) which determines a power output of the engine. The system further includes a control unit (38) which is configured to compare the determined power output with a value of a power threshold, and to command a reduction in fuel supplied to the engine when the determined power output exceeds the power threshold value. The system further includes a second engine sensor (42, 44) which measures the rate of change of rotational speed of the core engine (2) spool. The control unit (38) is further configured to adjust the power threshold value as a function of the measured rate of change of speed of the core engine (2) spool.
